Abstract: Human gait analysis is a crucial tool in healthcare, providing valuable insights into an individual’s well-being, as various disorders and diseases can be detected through changes in walking patterns. This study aims to validate the gait sensing results obtained from a smartphone, an easily accessible and portable device, by comparing them with equivalent data from the G-Walk, a widely used commercial equipment. The goal is to assess the applicability and accuracy of the solution with the support of healthcare professionals, ensuring its effectiveness in clinical settings.
